I'm 73. I functionally retired last January and completely in August. Despite having the luxury of no financial worries and being able to ramp down time over the two/three years prior I was still uncertain anxious about detaching entirely. Should not have worried. As I quickly realized, going to work at all had become an unwanted distraction. As said/implied by others...retirement is the best job I've ever had.

A perspective bit....During my back in the day, 40 to 60 hour work weeks every 15 minute home remodeling/maintenance job took all weekend. Today they only take me a couple of hours.

Congrats on your pulling the plug!
